Keep your climate system switching cleanly between fresh outside air and recirculated cabin air with the Four Seasons HVAC Recirculation Door Actuator, MPN 73701. This small electric actuator drives the recirculation door inside the HVAC case, and it drops in as a direct-fit replacement for the 2016-2020 Cadillac CT6. When a failed actuator is the cause of a door stuck on fresh or recirc, clicking behind the dash, or a blend that won't respond to the panel controls, this unit replaces it.
What it does: positions the recirculation air door on command, controlling whether the blower pulls in outside air or re-circulates air already inside the cabin.
- Internal components: motor, drive gears, electronics and connections.
- Includes: lever arm, gear, cam gear hardware and linkage where applicable.
- Tested: for function, durability and longevity, and built to OE-level fit and function.
- Backed by Four Seasons: over 50 years of mobile A/C experience.
Diagnose the root cause before replacing, since these symptoms can also come from the control head, wiring, or a bound door.
